Analysis of iodine content in salt at household level from 2009′s surveillance results in Xinyang City

目的了解信阳市居民食用碘盐情况,及时发现问题并采取相应的干预措施。方法根据《河南省碘盐监测方案》,碘盐生产、批发企业每月按东、西、南、北、中5个方位抽取一批9份盐样检测含碘量;居民户碘盐监测,在每县(区)按东、西、南、北、中划分5个方位抽取9个乡(镇、街道办事处),每个乡(镇、街道办事处)抽取4个行政村(居委会),每个村(居委会)抽取8份盐样,每县(区)共采集288份盐样检测含碘量。结果居民层次非碘盐率0.21%,碘盐覆盖率99.79%,碘盐合格率97.18%,合格碘盐食用率96.98%。结论从碘盐质量指标上看,信阳市已提前完成了全市消除碘缺乏病目标;一些遍远地区还存在一定的非碘盐冲击和不合格碘盐食用情况,有向市区转移的趋势。
